1. Introduction
Just 24 hours ago, the American Institute of Architects highlighted a surge in sustainable commercial projects using corten steel facade systems—underscoring how metal clad exteriors are reshaping modern design with durability and low maintenance. This trend reflects growing interest in resilient, eco-friendly building materials.
If you’ve heard terms like ‘metal clad roof,’ ‘steel clad house,’ or ‘clad steel’ but aren’t sure what they mean, you’re not alone. ‘Metal clad’ is a versatile phrase used across construction, manufacturing, and electrical engineering. In this guide, we’ll break down exactly what metal clad means, where it’s used, and why it matters.
2. What Does Metal Clad Mean?
At its core, ‘metal clad’ (or ‘metalclad’) refers to a surface, structure, or component that’s covered or layered with metal. The ‘clad metal meaning’ involves bonding two or more metals together—often for enhanced strength, corrosion resistance, or aesthetic appeal.
For example, aluminum clad steel combines the lightness of aluminum with the strength of steel. Similarly, stainless clad aluminum offers corrosion resistance with thermal efficiency. This process can be achieved through rolling, explosion bonding, or electroplating.
3. Metal Clad in Architecture
In building design, metal clad systems dominate modern exteriors. From sleek office towers to minimalist homes, architects choose metal for its longevity and visual impact.
Popular options include:
- Metal clad wall panels for clean, industrial aesthetics
- Metal clad roof systems like colorbond standing seam or pac clad standing seam roof
- Corten steel siding, prized for its rust-like patina and low maintenance
- Zinc facade and copper siding for timeless, evolving finishes
- Exterior corrugated metal siding and vertical standing seam metal siding for texture and rhythm
A steel clad house often features a corrugated steel facade or standing seam facade, blending ruggedness with refinement. Meanwhile, details like pac clad column covers or pac clad coping add polished finishing touches.
4. Common Metal Cladding Materials
Not all metal cladding is the same. Material choice affects cost, performance, and look.
Corten steel siding cost varies by region but remains popular for its self-protecting oxide layer. Zinc metal siding and zinc clad roof options offer natural weathering and recyclability. Aluminum clad sheet (or aluminium clad sheet) is lightweight and corrosion-resistant—ideal for coastal environments.
For high-end projects, titanium clad or copper nickel clad deliver unmatched durability. Even dormers get the treatment—zinc clad dormer elements add subtle elegance.
5. Industrial and Technical Uses of Clad Metals
Beyond buildings, ‘clad metals’ play a critical role in engineering. Clad steel might refer to a carbon steel plate bonded with stainless steel for chemical resistance—common in boilers or pressure vessels.
Aluminum clad stainless steel and stainless clad aluminum are used in heat exchangers. Alloy clad materials like 2024 T3 clad or 7075 T6 clad serve aerospace needs.
Metal clad wire—such as aluminum clad steel wire, cu clad wire, or aluminum clad wire—is widely used in telecommunications and electrical grounding due to its conductivity and strength.
Metal clad electrical wire (often called MC cable) is permitted in commercial buildings in Pennsylvania and many other regions, especially where mechanical protection is needed.
6. Metal Plates and Sheets in Cladding Systems
Many metal clad applications start with base materials like steel plate, stainless steel plate, or aluminum plate.
Common types include:
- Mild steel plate and boiler plate steel for structural backing
- Stainless steel metal plate (e.g., 316 stainless steel plate or 304L plates) for corrosive environments
- Aluminum diamond plate or aluminum tread plate for slip-resistant surfaces
- Perforated plate or diamond plate sheet metal for decorative screening
Thickness matters too—1/8 inch steel plate, 3/16 metal plate, or thick steel plate selections depend on load and exposure. You’ll often see ‘steel plate for sale’ listings specifying ASTM A387 or alloy grades like 4140 or Inconel 718 plate for extreme conditions.
7. Sustainability and Future Trends
Metal cladding is inherently sustainable—most metals are 100% recyclable. Recent projects favor corten siding cost efficiency and zinc’s longevity. Innovations like Inconel weld overlay or chrome carbide overlay extend equipment life in harsh industrial settings.
Even insulation gets the metal treatment: aluminum clad pipe insulation and metal clad insulation improve thermal performance in HVAC and process piping.
8. Conclusion
Whether you’re designing a metal clad building, specifying clad metals for machinery, or choosing metal clad siding for your home, understanding the range of options—from corten steel plate to pac clad HWP systems—is key. Metal clad isn’t just a trend; it’s a smart, durable, and increasingly sustainable choice across industries.
